I'd have to go with fluorine.
Fluorine.
Florine.
Bromine (Br) is a liquid at room temperature and is a non-metal. The only liquid element that is not a metal is Bromine (Br). There is one other element that occurs in liquid form and that is Mercury (Hg).
Fluorine is a non metal element. Mass number of it is 19.
First of all, all halogens are non-metals. Secondly, the most reactive is fluorine, which reacts to nearly everything, hence it is rare. After fluorine comes chlorine, then bromine and iodine.
Sulfur is a non metal element. There are 16 electrons in a single atom.
the diamond is the heaviest non metal
Fluroine is the most reactive non-metal.
fluorine
Fluorine is the most reactive non metal.Caesium is most reactive metal in the table.Fluorine has atomic number 9.
A reactive non metal is an element that can gain the electrons or is more electronegative
Fluorine is the most reactive non-metal.
The most reactive non-metal is fluorine. It is often nicknamed the 'Tyrannosaurus Rex' of the elements because of its reactivity. NB . Oxygen ,which we breath, is also a very reactive element. If it wasn't so reactive we would probably die.
caesium is the most reactive non-radioactive metal and Florine is the most reactive non-metal, but francium is the most reactive, radioactive metal
A reactive non-metal.
fluorine is the most reactive non metal in the periodic table.
It is the most electronegative halogen, meaning it wants electrons the most making it reactive
"very reactive"
Most elements are non reactive to noble gases.
